Abstract: A method for producing a pneumatic module, a gas analysis device comprising at least one such pneumatic module, a computer program product via which the operating characteristics of a corresponding pneumatic module can be simulated, wherein the pneumatic module serves to adjust a fluid flow and is deployable in the gas analysis device and includes a support sleeve and a flow module that is contained in the support sleeve, where the flow module is connected at a first end thereof to the support sleeve in order to achieve greater measuring accuracy of the gas analysis device.

Abstract: A flame ionization detector includes a burner to combust an oxygen-containing sample gas in a gas flame in the presence of air and while supplying a hydrogen-containing combustion gas. A measurement device measures an ion current from the gas flame to an electrode, and a temperature sensor measures a temperature of the gas flame. An evaluation device evaluates the measured ion current and compensates during evaluation of the measured ion current for a cross-sensitivity of the ion current to oxygen in the sample gas using the measured temperature of the gas flame.

Abstract: A fluid-cooled balun transformer that includes a substrate plate with a first and an opposite second face, a first and a second conductive element arranged on the first and the second face, respectively, wherein a first and a second signal port electrically is connected to the first and the second conductive element, respectively, and a cooling module, where the second conductive element is transformingly coupled to the first conductive element and electrically isolated therefrom, the cooling module includes a first tubular member, the first tubular member has a fluid inlet to receive a coolant fluid into the first tubular member, a flow channel to conduct a flow of coolant fluid within the first tubular member and a fluid outlet to release the coolant fluid from the first tubular member, and where the flow channel of the first tubular member is arranged in thermal contact with the first conductive element.

Abstract: A measurement arrangement includes four electrically heated resistors which are arranged in gas paths and are connected to form a Wheatstone bridge, where each of two resistors which are diagonally opposite each other in the Wheatstone bridge are contained in a respective component arranged on a common heated carrier, each respective component is assigned to one heating resistor arranged near the component on the carrier, and where an unbalanced state of the Wheatstone bridge is compensated for by variably energizing the heating resistors.
